The FlyHLLAPI DLL is provided with the Flynet Viewer to provide customers with a migration path for existing HLLAPI/EHLLAPI/WinHLLAPI applications.
Many applications have been constructed for client/server and other PC environments using traditional terminal emulators and the HLLAPI interface.
HLLAPI was originally developed by IBM when the first 3270/PC was introduced and has since gone through a number of enhancements with the most popular implementation now the WinHLLAPI interface.
For new applications, the use of HLLAPI is not recommended, and the Flynet Viewer COM interface is preferred. This is due to the greater scope of built-in functionality present in the COM interface, as well as a cleaner programmer interface for VB, VBScript, Javascript and .NET developers.
The next section provides more information on when and why you would utilize the FlyHLLAPI DLL.
